Abstract: PURPOSE:To instantaneously obtain the result of measurement by providing a light shielding member being rotatable centering around an optical axis as a center in optical path of a light receiving system, and measuring the eye refracting power from each light quantity distributing state on a photodetector in three rotational positions of the light shielding member. CONSTITUTION:When a diopter value of an eye 3 to be examined is a negative value compared with a reference value, the image of a light source 4 is formed in front of an eyeground 7, and on the eyeground 7, a luminous flux 10 reflected by one point on an optical axis is condensed on the side of the eye 3 to be examined, and the upper half of a luminous flux projected onto a photodetector 9 by an objective lens 8 is brought to light shielding. On the other hand, when the diopter value of the eye 3 is a positive value compared with the reference value, the image of the light source 4 is projected so as to be formed in the rear of the eyeground 7, and the luminous flux 10 reflected by the eyeground 7 is condensed on the side of the element 9. As for the luminous flux projected to the light receiving surface 9a, the diopter value is derived, based on a light quantity distributing state varied by the diopter value of the eye 3 against the reference diopter value. Subsequently, in a computing element 13, the light quantity distribution of the luminous flux formed on the light receiving surface 9a is detected, based on a signal from the element 9, and the result of operation is displayed on an indicator 14.

Abstract: PURPOSE: To obtain high efficiency by determining a suction flow rate is near the region of a target flow rate given responding to load fluctuations of a plant or far from the region and by controlling the flow rate according to the decision and promptly accomplishing the target flow rate.  
     CONSTITUTION: A control unit 23 first receives signals from detectors 20W22. These signals allow the control unit 23 to calculate a flow rate Qs and an efficiency η at that time. The flow rate Qs and the target flow rate are compared. When the suction flow rate belongs to the region far from the target flow rate, an operation volume responding to the present flow rate is selected from a contol table which stores a preset flow rate and the operation volume is transferred to a drive unit 19. The drive unit 19 operates inlet guide vanes 11W14 and quickly accomplishes the target flow rate. When the flow rate is near the target flow-rate then, a control volume which is required to make the operation unit to improve its efficiency is determined. This makes it possible to perform highly efficient operation.
